Correction..
second time I used the following code to test. Then I got the above
IllegalStateException issue.
w = new QueryParser(null, new WhitespaceAnalyzer()).parse("*B:\"1 2\"*");
not the below one.
w = new QueryParser(null, new WhitespaceAnalyzer()).parse("*\**"B:1 2\"*");
Can someone point out the correct way to query for StringFields?
Thanks,
